Asteronotus spongicolus is a very cryptic dorid. The elongated body ranges in colour from
brown to yellowish, the mantle can be smooth or with tubercles,
there are a pale median line and white spots on the mantle. The rhinophores and gills
are difficult to see. This species is mainly recognisable from the sponge it is
living and feeding on: Carteriospongia.
You have to look for the animals on the underside of these sponges.
Very similar is Asteronotus mimeticus
which has an oval body and no median pale line on the mantle.
